Tumescent Infiltration Cannula – Threaded Fitting

The Tumescent Infiltration Liposuction Cannula with Threaded Fitting is a blunt-tip, multi-hole cannula used to deliver tumescent or wetting solution into the subcutaneous plane before liposuction. Instead of a Luer hub, the shaft ends in a machined screw thread that seats directly into a threaded handle or tubing connector, giving a rigid, wobble-free joint. It suits surgeons using handle-based infiltration systems and is supplied in bulk to distributors worldwide. See the full Tumescent Infiltration Liposuction Cannulas range for other fittings.

Buyers also search for this instrument as a screw-fit tumescent cannula, a threaded hub infiltrator, or a wetting solution cannula.

Screw-Thread Tumescent Cannula for Handle-Based Infiltration Systems

A threaded fitting turns the cannula and the handle into a single rigid unit. There is no rotational play at the joint, so the direction the surgeon points the handle is exactly the direction the tip travels. Over the long passes used in body infiltration, that rigidity gives better control of the plane than a push-on connection.

How the Port Pattern Works

The working section carries many small round holes spread in a staggered pattern along the shaft rather than grouped near the tip. Each hole releases a small share of the solution, so a single pass wets a long column of tissue evenly instead of pooling fluid at one point. The staggered layout means the openings do not sit in one straight line, so solution leaves the shaft on more than one side and spreads through the plane rather than tracking along a single channel.

The distal tip is closed and rounded. It separates the subcutaneous plane by blunt dissection as the cannula advances, pushing vessels and nerves aside rather than dividing them, which is why an infiltration cannula is not simply a long needle.

Key Features

• ✔ Even wetting of a long tissue column in a single pass
• ✔ Closed blunt tip separates the plane without cutting vessels or nerves
• ✔ One-piece German stainless steel shaft, fully reusable
• ✔ Custom diameters, lengths and hole patterns available on request

Specifications

Clinical Applications

• Tumescent infiltration before body liposuction of the abdomen, flanks, back and thighs
• Wetting solution delivery before power-assisted and syringe liposuction
• Arm, neck and submental infiltration with the shorter, smaller-diameter sizes
• Donor site infiltration before fat harvesting for grafting

Material and Sterilization

The cannula is made from German stainless steel with a passivated surface that resists corrosion and pitting through repeated cleaning cycles. It is reusable and can be steam autoclaved at 134°C. Flush the lumen and every hole with clean water immediately after use and dry fully before autoclaving. A cannula with many small openings needs more attention here than a two-port design, because dried tumescent solution blocks small holes first and an uneven port flow shows up as uneven infiltration.

How to Choose

Order the threaded fitting if you already own handles that take a screw-in cannula, and send us your handle specification before ordering in quantity. Diameter sets the flow rate and length sets the reach. For large-volume body infiltration of the abdomen, flanks, back and thighs, the 2.5mm to 4.0mm diameters in 25cm to 35cm are the usual working range, because they fill a large area in fewer passes. The 1.8mm to 2.5mm range in 15cm to 25cm suits arms, the neck and smaller regions. The 1.0mm to 1.5mm diameters in 5cm to 12cm are for facial and submental infiltration, where thin tissue needs a small-diameter cannula. Match the fitting to the syringe, pump or handpiece already in your theater.

Why Buy Direct From the Manufacturer

Manufactured by Healermed Instruments, a surgical instruments manufacturer and exporter based in Sialkot, Pakistan. Factory-direct pricing removes the importer and distributor layer. Production runs under an ISO 13485 and FDA CGMP quality system, with ISO 9001 and CE Mark certification. OEM manufacturing and custom branding are available for distributor and brand-owner orders.

Frequently Asked Questions

What is a threaded fitting tumescent cannula used for?

It is used to deliver tumescent or wetting solution into subcutaneous tissue when the cannula screws into a threaded reusable handle rather than attaching to a syringe. The screw thread creates a rigid joint with no rotational play, which helps the surgeon hold the intended plane over long passes.

What is the difference between a tumescent infiltration cannula and an aspiration cannula?

An infiltration cannula delivers fluid into tissue; an aspiration cannula removes fat under vacuum. Infiltration cannulas are narrower, carry many small holes for even fluid spread, and connect to a syringe or pump. Aspiration cannulas have fewer, much larger ports designed to draw fat and connect to a vacuum line.

Why does this cannula have so many holes?

Many small holes spread the solution along the whole length of the pass instead of releasing it at one point. That gives a more even wetting of the treatment area, fewer passes to fill a large region, and less risk of a fluid pocket forming where a single port sat. The staggered layout also sends solution out on more than one side of the shaft.

Is this cannula autoclavable?

Yes. The instrument is fully reusable and can be steam autoclaved at 134°C. Flush the lumen and every hole with clean water immediately after use, remove all residue before sterilization, and dry completely. Check the holes under light before each cycle, since a blocked opening changes how the solution distributes on the next case.

What is the minimum order quantity for bulk orders?

The minimum order quantity is agreed per order rather than set at a fixed number. Send us the sizes, fittings and quantities you need through the wholesale request page and we will confirm the minimum for that specification. This lets a small distributor start with a trial order and a larger importer scale up on the same terms.

Do you provide samples?

Yes. Samples are available on request and the buyer covers the shipping charges. Send us your handle specification along with the diameter and length you want to evaluate. Testing a sample first is the safest way to confirm the thread seats correctly in your handle.

Can I order a custom size?

Yes. Custom diameters, working lengths, and hole patterns are available on request in addition to the standard size grid. Send your specification through the wholesale request page and our production team will confirm what can be produced. Custom branding is also available for distributor and OEM orders.
